Is Your Water Heater Less Efficient? Sediment Build-Up is to Blame

water heating systemWater heaters are a vital part of properties worldwide. Like all appliances, however, they are plagued with various issues from time to time. Among the most common water heater issues is sediment build-up.

The exact amount and rate of sediment build-up depend on your water’s hardness and your tank’s self-cleansing mechanisms. Specialists from Expert Plumbing, Heating, Air and Electrical, as well as other water heater repair experts from Orem, enumerate the effects of sediment build-up on a heater’s operation.

Lowered Heating Efficiency

Gas water heaters heat water in the tank using a flame located at the bottom. The sediments accumulated at the bottom of your tank will need to be heated first before your water gets the heat. This ultimately results in high energy costs to heat the solids and in most cases, an output of lukewarm water.

Water Displacement

When buying your water heater, the tank’s capacity is an important consideration. Sediment build-up causes water displacement and hence reduces your tank’s capacity. A build-up of approximately 10 gallons reduces your tank’s capacity by about 25%. Even a small reduction in your tank’s capacity will still impact your tank’s holding capacity and output significantly.

Damage to Your Heating Elements

Sediment accumulation poses a significant hazard to an electric water heater’s heating elements, which are located near the tank’s bottom. With high amounts of sediment covering it, expect failure or burnout.

With these negative effects of a sediment build-up on a water heater, managing it promptly is essential. The first indicator of sediment build-up is typically a banging sound when you switch on your heater. This should prompt you to call a plumber right away.
